Rule 9-3-2

[dg1980]

Dear MISRA team,

i think in the example below, the non-const get_p is a violation of this rule, while the static analysis tool says otherwise.
The compliant example in the document refers to shared data, which is not the case here.
I think it was misinterpreted as "returning a member of type T* is always compliant".
If so, maybe in the next version of the standard this rule needs a better formulation in terms of exceptions.
